Some mysteries are unsolvable. The second shooter, Area 51, the alpha predator of the deep ocean, the Dolphins’ insistence on using the run game rather than exploiting a weak pass Ravens defense last week. Sometimes, there are no answers.

Case in point: How has perennial afterthought Doug Baldwin suddenly turned into a fantasy star? Is it real, or is he just a fantasy Bigfoot, a momentary clamor inspired by a “sighting,” only to be dismissed as fodder once those sightings ebb? Has he been Nessie, swimming in the deep loch waters for five years before waiting to reveal himself, or will he retreat to fantasy oblivion like a UFO on the horizon?

Baldwin’s track record is consistent. Outside of 2012, Russell Wilson’s rookie year, when Baldwin missed two games, every year has been close to the same — around 800 receiving yards, 50 some-odd catches (he had a career-high 66 last season) and three to five touchdowns.

This year has been a slight improvement. He has 778 receiving yards, which already matches his 2011 and 2013 seasons. He has 55 catches, his second-best season. And he has eight touchdown grabs, easily the most of his career.

And he has four games left. Of those four games, two are against weak pass defenses. The two strong opponents come in Week 17, after your fantasy playoffs likely are finished, and Week 16 against a reeling Rams team not nearly as good as its ranking.

Start with the Ravens this week. Baltimore’s pass defense has been dreadful (fifth-most fantasy points allowed), but its run defense is solid (fourth-fewest fantasy points) — which makes Miami’s game plan last week all the more confusing, or stubbornly stupid, take your pick.

Next are the Browns, who are even worse at defending the pass than the Ravens are. Then the overrated Rams squad. That’s a schedule that screams for this year’s fantasy playoff difference-maker.

Add in that the Seahawks are fighting for a playoff spot and are missing primary running back Marshawn Lynch and superstar tight end Jimmy Graham (even if they weren’t using him correctly), and you have is a team with a juicy schedule, the need to play it out, and the strategic motivation to lean on the passing game.

Baldwin should be considered a strong WR2 in virtually every format, and is a valuable target in daily leagues (DraftKings $4,500, FanDuel $6,800).

But before you leap to keeper thoughts, realize four and a half years of shrug-inducing stats are more reliable than eight weeks of stardom. Like the Yeti of Himalayan lore, expect Baldwin to disappear into the waiver wire hinterlands come next season.

For now, do what the UFO spotters never do, take a picture, put Baldwin in your lineup, amass evidence so one day you can say, yes, Doug Baldwin was a fantasy beast, not just a myth. And you will have the wins to prove it.

Jameis Winston, QB, Buccaneers

vs. Saints (DraftKings $5,500/FanDuel $7,800)

In the past six games, the Saints have allowed 24 touchdown passes, including four or more four times. No single player in fantasy football is more reliable than the quarterback playing against the Saints.

Shaun Draughn, RB, 49ers

at Browns (DK $4,800/FD $6,500)

He is getting the touches to justify attention, even if he does play on a dysfunctional offense. The Browns’ recent resurgence defending the run is cancelled out by Draughn’s usage in the passing game.

Allen Hurns, WR, Jaguars

vs. Colts (DK $5,500/FD $6,600)

Out with a concussion last week after nursing other ailments the weeks prior. He had scored in seven straight games before injury woes. He will get back to raking against a mediocre Indianapolis pass defense.

Coby Fleener, TE, Colts

at Jaguars (DK $3,000/FD $4,900)

Remember that time you hooked up with someone late at night thinking they were hot, only to find out the next day they weren’t? Well, Fleener is hot on Sunday against a Jags defense that has given up six tight-end touchdowns in the past four games, but he’s not so hot any other time.

Philip Rivers, QB, Chargers

at Chiefs (DK $6,000/FD $7,600)

Think Tom Brady has it bad? Rivers has it worse. Banged up O-line. Triage crew at WR. No running game to take speak of. Right now, the Chargers might be the worst team in the NFL.

Chris Ivory, RB, Jets

vs. Titans (DK $5,000/FD $7,100)

Without the big touchdown run at the end of the Week 12 Miami game and a two-touchdown day when he rushed for 26 yards on 23 carries against the Jags in Week 9, he would be in a seven-week slump.

Amari Cooper, WR, Raiders

at Broncos (DK $6,200/FD $6,900)

Cooper has had an incredible rookie season, but somehow has not been an incredible fantasy player. Against the top pass defense in the league … well, you know the rest.

Richard Rodgers, TE, Packers

vs. Cowboys (DK $3,900/FD $5,600)

Remember that time when you hooked up with the ugly person just because they were the only one left at the bar? Don’t you regret it? Well, you’ll regret playing Rodgers this week against a Cowboys team that does a decent job defending tight ends.

The decision

Drew: Manziel — The Colts’ backfield, with Hasselbeck and running back Frank Gore, is top-notch … five years ago. The primary receivers, T.Y. Hilton and Donte Moncrief, likely are as much a product of Andrew Luck as their individual talents. It’s a great matchup for Hasselbeck, but give me the kid with something to prove, on a Browns team with nothing to lose and an offense with some complementary talent in the passing game against a weak 49ers pass defense.

Jarad: Hasselbeck — Though it’s not 2007, there are several reasons Hasselbeck is worth streaming — starting with the fact the Jaguars are allowing the second-most fantasy points to opposing QBs and 264.6 passing yards per game (seventh-worst). The last time Hasselbeck played the Jags (Week 4), he threw 45 times for 282 yards and a touchdown. The Jags do a decent job against the run (103 yards per game), meaning Hasselbeck will be throwing: Jacksonville should easily stop a Colts rushing attack that has accumulated just 81 yards over the past two games and has no TDs since Week 9. With the Colts’ defense ranked third-worst against the pass, we should be looking at a high-scoring, pass-happy shootout between Hasselbeck and Blake Bortles. Hasselbeck will be helping you pop the cork after you win this week (Manziel would get in trouble for that).
